The compressor works under better conditions and compared with that of wind cool combination , the life can be doubled 壓縮機(jī)在更為良好的環(huán)境下工作,壽命比風(fēng)冷機(jī)組可延長(zhǎng)一倍以上。
The compressor works continuously to maintain the inside temperature , and the heat it ejects from the back of the fridge offsets the cold at the front 冰箱的壓縮機(jī)必須持續(xù)運(yùn)轉(zhuǎn),以保持里面的溫度,壓縮機(jī)從冰箱后面排出熱氣,與冰箱前面出來(lái)的冷氣相互抵消。
From the experimental , results it is observed that the adjustable inlet equipment can efficiently put off the occurrance of compressor surge and choke , and a wider range of flow in compressor working can be achieved 結(jié)果表明,可調(diào)導(dǎo)風(fēng)裝置能夠有效地延緩喘振和推遲阻塞的發(fā)生,擴(kuò)大了壓氣機(jī)流量范圍。
The analyzing result indicates that when the ambient temperature of compressor rises , the compressor works in an unfavorable ambient and the shell temperature and discharge temperature rise , while the performance and refrigeration capacity reduce . sealing the compressor can reduce the 分析結(jié)果表明:壓縮機(jī)環(huán)境溫度升高時(shí)壓縮機(jī)工作在一個(gè)十分不利的環(huán)境中,環(huán)境溫度的升高導(dǎo)致壓縮機(jī)的殼溫和排氣溫度升高,性能降低,制冷量減小。
At present , surge control method for centrifugal compressor being used is commonly by least - flow method . it can ’ t make compressor working within operating condition area , sometimes starts the surge control system earlier , which will waste energy sources and depress economy benefit . even , its control system commonly consists of simulation instrument , can ’ t modify the changing surge curve of compressor in time and can ’ t control nonlinear surge curve preferably 目前,在用的離心壓縮機(jī)的防喘振方法一般采用最小流量法,它不能充分使壓縮機(jī)工作在其工況區(qū),往往過(guò)早起動(dòng)防喘振系統(tǒng),浪費(fèi)了能源,降低了經(jīng)濟(jì)效益。且控制系統(tǒng)一般采用模擬儀表構(gòu)成,在壓縮機(jī)的喘振線發(fā)生變化時(shí)不能及時(shí)修正,對(duì)非線性的喘振線不能較好的實(shí)施控制。
